Type Concept: This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this alpine association occur on talus slopes and ridgelines at between 3500 and 3810 m (11,500-12,500 feet) elevation. Slopes are moderate to steep. Aspects are south and west, and sites are probably free of snow early in the season followed by a long, droughty summer. Soils are well-drained and gravelly with significant talus, scree, or cobble. This sparse alpine herbaceous vegetation is characterized by a low (<0.5 m) open canopy of forbs and graminoids. Podistera nevadensis is a diagnostic forb, occurring in 75% of stands. Elymus elymoides ssp. californicus is also diagnostic and one of the most common graminoids. Other common forb associates may include Phlox pulvinata, Eriogonum ovalifolium, Selaginella watsonii, Draba densifolia, Astragalus kentrophyta, and/or Erigeron pygmaeus. Graminoids present commonly include Festuca brachyphylla ssp. brachyphylla and/or Poa glauca ssp. rupicola.
